let's take this example as showed in the attachment:
What's the difference between
1-
Register with a key with: Expiration date of 31/03/2016
Or
2-
Register with a key with: Register after 31/03/2015 with limited days of 365 days
3-
Register with a key with: Register Before 31/03/2016
?
For me it seems like they're all the same? if so can we use the combination of all of them? for more security?
thanks
